SHUTTLE-MOTION FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 773,396, dated October25, 1904.

Application filed February 25, 1904. Serial No. 195,153. (No model 10(all whom, it 711/601] concern.-

Be it known that 1, WILLIAM F. Krnrznve, a citizen of the United States,residing at Hanover, in the county of York and State of Pennsylvania,have invented certain new and useful Improvements in Shuttle-Motionsfor. Looms; and I do declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of referen ce markedthereon, which form a part of this specification.

My invention relates to sh Little-motions for looms, and while designedwith particular reference to looms for weaving wire-cloth yet is adaptedfor looms weaving other material.

The invention has for its object to provide improved means for operatingthe shuttlebars and also to provide improved means for releasing theshuttle at the proper time for its transfer from one shuttle-bar to theother;

To the accomplishment of the foregoing and such other objects as mayhereinafter appear the invention consists in the construction and in thearrangement of parts hereinafter particularly described and then soughtto be clearly defined by the claims, reference being had to theaccompanying drawings, forming a part hereof, and in which Figure 1 is afront elevation of so much of a loom as is necessary to illustrate themanner of applying my invention thereto. Fig. 2 is a detail, on anenlarged scale, illustrating means for releasing the shuttle; and Fig. 3is a detailed view of one of the sheaves or pulleys, from which a chainextends to the crankshaft hereinafter mentioned.

In the drawings the numeral 1 designates a part of the loom-frame fromwhich is swung the lathe-frame 2, which carries the shuttlemovement andwhich comprises generally the shuttle-bars 3, adapted to slide in thebrackets 4:, the pitmen 5, which connect the shuttlebars with thecrank-arms 6, attached to the chain-wheels 7, journaled in the plate 8,so as to lie one on each side of said plate, and shaft 9, having cranks10 and 10, from which power will be transmitted to the chain-wheels 6,the

pitmen, and shuttle-bars by means hereinafter to be described. The shaft9 will be provided with cams to bear against levers connected by linksto heddle-frames, which parts 'zontally-disposed shafts journaled insuitable brackets 12 and boxings 13, secured to the lathe-frame 2. Theseshafts carry at their .inner ends grooved sheaves or pulleys 14 and 14,from which extend chains 15 and 15. which at their lower ends areconnected to the chain-wheels 7, one to each wheel. The opposite ends ofthe shafts 11 and 11 carry grooved sheaves or pulleys 17 and 17, fromwhich extend chains 18 and 18, which at their lower ends are attached tothe cranks lO and 10 of the shaft 9. As the shaft 9 revolves the crank10 at one end thereof will pull on the chain 18 so as to turri thesheaves 17 and 14: in a direction to wind one chain, 15, on the sheave14 and unwind the other chain, 15, from the sheave 14 and cause thechainwheels 7 to turn so as to move the pitmen 5 in directions whichwill cause the shuttle-bars 3 to reciprocate, one of which will carrythe shuttle 19 out and back, when it will be grasped by the hook of theother shuttle-bar and carried the remainder of its travel and then backto be caught by the other shuttle-bar, as usual in this type of looms,each shuttle-bar catching the shuttle on its outward movement after ithas been brought in by the companion shuttle-bar, the several partsbeing so p roportioned and relatively arrangedthat the bar receiving theshuttle will receive it at a point beyond the center or limitofitsinward movement and while on its outward movement, as illustrated,for instance, in Fig. l of the drawings. The bar from which the shuttleis released travels outward and then inward and again slightly outwardbefore it receives the shuttle from the other bar which has carried itoutward and brought it back to a point i where it will be received bythe other bar and at the same time released from the bar carryl ing it,for which purpose the double chainwheel 7 will make nearly a completerevolution---ifor instance, say lifteen-sixteenths of a revolution inone direction and then in the other direction. By arranging the sheaves14 14 and 17 17" as illustrated the chains 15 and 18 18" will runtherefrom in straight lines, as shown, so that there will be lessfriction and there will be no liability of the chains being pulled fromoff their sheaves and the parts will run easier and with less noise.

In order to take up the slack in each chain 18 18 in the upward movementof the chain, 1 form the sheaves 17 and 17 cam-shaped, as illustrated inFig. 3, so that the slack will be taken up by said cam in the winding ofthe chain around the sheave, and thus rattling will be prevented and asteadier movement obtained.

The hollow shuttle-bars 3 each contain a rod 19, which at its inner endis connected with a hook 20 say through the instrumentality of a slidingblock 21 and pin 22, as in my Patent No. 737,939, or otherwiseand at itsouter end is connected to a bent lever 23, which is pivoted to an arm24, extending from a member 25, which connects the pitman 5 with theshuttle-bar. One arm of the lever 23 loosely encircles or straddles therod 19 and is limited in its movement by the shoulders or collars 26 onthe rod. The outer end of the lever 23 extends toward and is in linewith a cam 27 and carried by the lathe-frame 2. 'When on the inwardmovement of the sh Little-bar it reaches the point for the release ofthe shuttle, the inturned arm of lever 23 strikes the cam 27 and ridesover it, so that y the end of the lever is raised and the other endthrown outward, so as to shift the rod 19 outwardly, and thus lift thehook 20 and unlock the shuttle it is grasped by the corresponding hookof the other shuttle-bar. hen ,5 on the outward movement of theshuttle-bar the lever leaves the cam 27, the spring 28,

which was compressed in the other movement of the rod, now expands andreturns the rod and the hook to their normal positions. This makes asimple and durable and easy-working means for actuating theslnittle-holding hook. l have illustrated and described withparticularity the preferred details of construction and arrangement ofthe several parts; but it is to be understood that changes can be madetherein and essential features of my invention be retained.

Having described my invention and set forth its merits, What 1 claim is1 In a shuttle-motion for looms, the combination of the reciprocatingshuttle-bars, pitmen for transmitting motion to said bars, rotatablemeans connected with said pitmen, shafts carrying sheaves at oppositeends, chains connecting one set of said sheaves with said rotatablemeans, and chains connectingthe other set of sheaves with mechanism forrotating the sheaves, substantially as described.

2. In a shuttle-motion for looms, the combination of the reciprocatingshuttle-bars, pitmen for transmitting motion to said bars, rotatablemeans connected with said pitmen, shafts carrying sheaves at oppositeends, chains connecting one set of said sheaves with said rotatablemeans, and chains connecting the other set of sheaves with mechanism forrotating the sheaves, one set of sheaves having cams for taking up slackin the chains, substantially as described.

3. In a shuttle-motion for looms, the combination of the reciprocatingshuttle-bars, pitmen for transmitting motion to said bars, rotatablemeans connected with said pitmen, sheaves provided with chains connectedat one end to the sheaves and at the other end to said rotating means,and mechanism for rotating said sheaves to wind the chain upon onesheave while unwinding the chain from the other sheave, substantially asdescribed.

4. In a shuttle-motion for looms, the combination with the shuttle-bars,and mechanism for reciprocating same, of longitudinallymoving rods eachprovided with a hook for engaging the shuttle, a bell-crank leverpivoted to a part carried by the shuttle-bar and having one armconnected with the shuttlehook rod, and a cam in the line of travel ofthe lever to engage one arm thereof to tilt the lever to release thehook from the shuttle, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
